If you are ajailed and you take up the space of a person who could otherwise be RPing ie the server is 120/120, then you will be kicked. Admins like promoting activity and RP, if there are 120/120 people online, but 15 are afk, 10 in ajail and then there's 5admins not-RPing but sorting out /assistances and /reports then infact you have maximum 90people online who are RPing!!!
Getting rid of all those afk and ajailed and you can move that number a large amount! Hell it'll be a great day when we can have 120 people RPing at once
